If your site produces hazardous waste, the paperwork is as important as the waste itself. The hazardous waste consignment note is the legal document that must travel with your waste from the moment it leaves your premises until it reaches its final destination. Site managers who overlook this requirement can create serious compliance problems for their business.
This guide explains what a hazardous waste consignment note is, when it is required, how it is organised, and what your responsibilities are as a site manager.
What is a hazardous waste consignment note?
A hazardous waste consignment note, often shortened to HWCN, is a legally required document that details the transfer of hazardous waste from one party to another. It is a legal document that accompanies the transport of hazardous waste in the UK and records important information about the waste, including what it is, where it has come from, and where it is being taken.
The requirements are clear: you must use consignment notes to move hazardous waste, and a completed consignment note must accompany hazardous waste when it is moved from any premises. This is not optional paperwork. It is a condition of moving hazardous waste at all.
When is a consignment note required?
In most cases, if you move hazardous waste to or from any location within Wales you must prepare a hazardous waste consignment note. The same principle applies across England and Wales: a completed consignment note must accompany hazardous waste when it is moved from any premises, whether it is being taken for treatment, recycling, or disposal.
This means the note is needed at every point where hazardous waste changes location. The waste must be accompanied by the consignment note until it reaches its final destination. Importantly, you need to use one consignment note per vehicle, so a collection involving several vehicles requires a note for each one.
Site managers should also remember that the consignment note does not stop being relevant once the waste is loaded onto a lorry. It must stay with the waste throughout the entire journey, and it must remain available until the waste arrives at the consignee’s site.
Who must complete the consignment note?
The consignment note is not something that the waste producer can delegate entirely to a carrier. The note consists of five parts, labelled A to E, and each part must be completed by every person or business involved in moving the waste. That includes the producer or holder of the waste, the carrier transporting it, and the consignee receiving it.
In practice, this means the producer or holder cannot simply sign a blank form and hand it over. Everyone involved in the movement has a duty to complete the relevant sections, and the paperwork must be accurate before the waste leaves the site.
How the consignment note is organised
The structure of the note is straightforward once you understand how the five parts and the colour-coded copies fit together.
The five parts of the note
The note is divided into five parts, labelled A to E. Each part captures information about the waste and its movement, and every party involved must complete all five parts. This structure ensures that the full journey of the waste is documented from start to finish.
Because every party completes every part, the consignment note builds a complete and consistent record of the transfer. This is important for regulators, who use the note to check that hazardous waste is being handled lawfully and tracked properly from production to final disposal.
Colour-coded copies
The consignment note uses colour-coded copies so that each party knows which version they should hold. The white copy is for the producer, holder, or consignor. The yellow copy is for the carrier. The pink copy is for the consignee.
When you prepare the note for a waste movement, make sure each party receives the correct copy. The carrier should carry their yellow copy with the load, while the producer or holder keeps the white copy on file and the consignee retains the pink copy when the waste is accepted.
How to complete a hazardous waste consignment note
To complete the note correctly, all five parts must be filled in by everyone involved in the movement. The producer or holder of the waste must complete their sections before the waste can be collected, and the carrier must complete theirs before taking the load. When the waste arrives at its final destination, the consignee completes their sections to close out the note.
Site managers should treat the consignment note like any other legal document. Information must be accurate, legible, and consistent across all parts. If details are missing or incorrect, the note could be rejected, and the waste could be left without valid documentation.
You should also check the official guidance in your area before setting up your consignment note procedures, because requirements may differ between England and Wales. Natural Resources Wales and the Environment Agency both publish guidance on how to complete hazardous waste consignment notes, and their instructions are the ones to follow.
Practical rules for moving hazardous waste
Once the consignment note is completed and the waste is loaded, a few practical rules apply. The hazardous waste must be accompanied by the consignment note until it reaches its final destination. The note cannot be filed away at the point of collection or sent on separately; it has to travel with the load.
You also need to use one consignment note per vehicle. If more than one vehicle is involved in moving hazardous waste from your site, each vehicle must have its own note. This applies even if the waste comes from the same premises and is going to the same destination.
When the waste reaches its final destination, the consignee keeps their copy of the note. The carrier retains their copy, and the producer or holder keeps theirs. This three-way record means the movement of hazardous waste can be traced from start to finish, which is exactly what regulators expect.
Why accurate paperwork matters
Hazardous waste is regulated because it poses a risk to human health and the environment if it is not handled correctly. The consignment note is the mechanism that allows regulators to track hazardous waste from production to disposal, which is why it is a legal requirement rather than a recommendation.
For site managers, accurate consignment note paperwork is part of running a compliant site. It also protects your business if there is ever a dispute about where waste came from, who carried it, or where it was disposed of. A complete set of consignment notes provides a clear audit trail for every load of hazardous waste that leaves your premises.
If you produce hazardous waste only occasionally, it can be tempting to treat the paperwork as an afterthought. In practice, the consignment note is the first thing a regulator may ask to see, and getting it right should be part of your standard waste procedure.
Working with waste management partners
Many site managers rely on their waste contractor to handle the practicalities of hazardous waste collection and disposal. A reputable waste management company will understand consignment note requirements and will usually manage the documentation as part of the collection service.
However, the legal responsibility does not disappear simply because a contractor is involved. The note must still accompany the waste until it reaches its final destination, and all parties involved in the movement must complete their parts. Site managers should confirm that their waste contractor provides the correct documentation and that the completed notes come back for their records.
For businesses that generate hazardous waste on a regular basis, it is worth building the consignment note process into a broader waste management system. This includes knowing which waste streams are hazardous, planning collections so that each vehicle has its own note, and keeping organised records that can be produced quickly if requested.
Frequently Asked Questions
Here are the questions site managers most often ask about hazardous waste consignment notes.
How do I complete a hazardous waste consignment note?
You must complete all five parts of the note, labelled A to E. Each part must be completed by every person or business involved in moving the waste, including the producer, carrier, and consignee. Once complete, the white copy stays with the producer or consignor, the yellow copy travels with the carrier, and the pink copy goes to the consignee. The note must accompany the waste until it reaches its final destination.
How long do I need to keep hazardous waste consignment notes?
Guidance confirms that the consignment note must accompany hazardous waste until it reaches its final destination. Site managers should also keep copies of completed notes for compliance purposes, but the specific retention period is set by the relevant regulator, such as the Environment Agency or Natural Resources Wales. Check the current guidance for your location to confirm how long records must be retained.
What is the difference between a waste transfer note and a consignment note?
A hazardous waste consignment note is the legal document that must accompany hazardous waste when it is moved from any premises. It records important information about the waste and stays with it until final disposal. Other waste movements may require different documentation, and the rules differ depending on the waste stream. Check the guidance from the Environment Agency or Natural Resources Wales to confirm which document applies.
Do I need a separate consignment note for each vehicle?
Yes. The guidance states that you need to use one consignment note per vehicle. If hazardous waste is collected from your site in more than one vehicle, each vehicle must carry its own completed note. The note must accompany the waste until it reaches its final destination, so the carrier must keep it with the load throughout the journey.
